Currently 'dsp' configuration is intended for audio firmware but it doesn't work well with board level DTs (e.g imx8mp-evk) because board level DT enables audio related IPs (e.g SAI) while audio firmware needs this IPs disabled (because firmware will configure them). So, configure 'dsp' node to be used with rproc. This way users will be able to use board DT to use the DSP as long as they don't clash with Audio IP configurations. More comples usage of 'dsp' node (e.g by audio firmware) will need to create a separate dts file (or an overlay). This change follows the approach taken for other i.MX8 boards in commit 391a319c81f6d7 ("arm64: dts: imx8-ss-audio: configure dsp node for rproc usage") Signed-off-by: Daniel Baluta --- arch/arm64/boot/dts/freescale/imx8mp.dtsi | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/arch/arm64/boot/dts/freescale/imx8mp.dtsi b/arch/arm64/boot/dts/freescale/imx8mp.dtsi index 00924e0836db..2f94c55e4999 100644 --- a/arch/arm64/boot/dts/freescale/imx8mp.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8mp.dtsi @@ -280,7 +280,7 @@ reserved-memory { ranges; dsp_reserved: dsp@92400000 { - reg = <0 0x92400000 0 0x2000000>; + reg = <0 0x92400000 0 0x1000000>; no-map; status = "disabled"; }; @@ -2414,12 +2414,12 @@ usb_dwc3_1: usb@38200000 { }; dsp: dsp@3b6e8000 { - compatible = "fsl,imx8mp-dsp"; + compatible = "fsl,imx8mp-hifi4"; reg = <0x3b6e8000 0x88000>; - mbox-names = "txdb0", "txdb1", - "rxdb0", "rxdb1"; - mboxes = <&mu2 2 0>, <&mu2 2 1>, - <&mu2 3 0>, <&mu2 3 1>; + power-domains = <&pgc_audio>; + mbox-names = "tx", "rx", "rxdb"; + mboxes = <&mu2 0 0>, <&mu2 1 0>, <&mu2 3 0>; + firmware-name = "imx/dsp/hifi4.bin"; memory-region = <&dsp_reserved>; status = "disabled"; };
